Relaciones entre las aportaciones a la zona regable del río Jucar y la conductividad de la Albufera de Valencia.
2005
Las aportaciones a la zona regable del río Júcar condicionan la conductividad de la Albufera porque recibe las aguas sobrantes de riego. Se ha observado una relación inversa entre ambas variables. La demanda de agua para otras zonas pretende satisfacerse a partir del trasvase de los sobrantes de riego basándose en una mejora de la eficiencia del regadío. Estas actuaciones deben realizarse sólo cuando se aseguren previamente las aportaciones necesarias para mantener la calidad del lago. The water inflows to the irrigation area of the Júcar river determine the conductivity of the Albufera because it receives the surplus irrigation water. It has been observed an inverse relationship between bo…
Rainwater harvesting in urban areas of developed countries. The state of the art (1980-2017)
2020
Many urban areas suffer from water scarcity although paradoxically, a local source such as rainwater is mostly treated as a risk rather than a valuable resource. This change of paradigm is included in the 'integrated water resources management' and 'demand management' approach. The aim of this research is to identify and analyse studies that explore subject matters concerning rainwater in the integrated management systems of water resources into developed countries. The research methodology consisted in a literature review (from the 1980s to 2017) of territorial studies that examine rainwater harvesting in urban areas of the developed countries. To this end, a bibliometric analysis has been…
Inter-basin water transfer conflicts. The case of the Tagus-Segura Aqueduct (Spain)
2020
Since its inauguration in 1979, the Tagus-Segura Aqueduct has become one of the hydraulic infrastructures that have given rise to the highest number of inter-regional conflicts in Spain during recent decades. The aim of this paper is to analyse the political, social, environmental and economic conflicts presented in the donor (Tagus) and recipient (Segura) basins of this infrastructure. To this end, through the holding of interviews with the main stakeholders and an analysis of the regulations, an assessment has been made of the results (for and against) of those who defend maintaining this infrastructure, owing to its far-reaching social and economic impact, and those who advocate its imme…
Alfalfa crops amended with MSW compost can compensate the effect of salty water irrigation depending on the soil texture
2018
The availability of water resources of marginal quality such as drainage water or high-saltcontaining groundwater is turning into an important issue in Tunisia and other countrieswith scarce water resources. A pot experiment was carried out to evaluate plant produc-tion, nutrient content and heavy metal bioaccumulation in agricultural soils amended withMSW compost and irrigated with salty water, by using two different soil textures (clay andsandy). Salt water supply decreased plant dry yield in both soils. Salt stress had signifi-cantly reduction in plant biomass in sandy soil compared to those in clay soil (biomass ofdry weight is significantly higher in clay soil than those in sandy soil …
La crisis del modelo tradicional de regadíos del interior valenciano. El caso de Cortes de Pallás: paisajes del agua y patrimonio cultural
2020
Los sistemas tradicionales de regadío forman un legado que se manifiesta mediante lo que conocemos como paisaje y patrimonio del agua. En las áreas del interior valenciano se experimentan disfunciones socioeconómicas que se evidencian paisajísticamente. A partir del análisis en profundidad de un caso de estudio como es la huerta de Cortes de Pallás, en el sector septentrional del macizo del Caroig, se valora si los procesos en ella identificados explican las dinámicas de crisis de los regadíos históricos del interior. El abandono de una parte destacada de las parcelas ha sido una práctica común, aun manteniéndose su morfología y una red de acequias que sigue en funcionamiento. Els sistemes …
